Subject: [PATCH v2 0/3] riscv: mem= support, ioremap exec fix

Patch 1 was already sent separately. This improves it by calling
memblock_enforce_memory_limit in order to call set_max_mapnr with the
correct memory size.

There are two more patches in this series. One is a micro-optimization,
the other enables ioremap of executable memory. The latter will be
needed to enable the Jailhouse hypervisor on RISC-V.

  riscv: Add support for mem=
  riscv: End kernel region search in setup_bootmem earlier
  riscv: Fix crash when flushing executable ioremap regions
